PTFE, or Polytetrafluoroethylene, is a synthetic fluoropolymer with exceptional chemical resistance, making it suitable for demanding applications. Chemours, a spin-off from DuPont, originally invented PTFE under the brand name Teflon in 1938. This versatile plastic is hydrophobic, non-wetting, and can withstand high temperatures. Its properties can be further modified by adding fillers like glass fiber, carbon, or bronze. It is known as the "king of plastics".
Key features of PTFE include a low coefficient of friction, high heat resistance, and resistance to chemical agents and solvents. It is an excellent electrical insulator and is FDA-approved for food-safe applications. PTFE is used in various industries, including food and beverage, construction, chemical processing, automotive, and aerospace. Common applications range from non-stick coatings on cookware to pipe linings, seals, gaskets, and electrical wiring insulation. As of February 2026, the price of PTFE ranges from US$7.79/KG in Northeast Asia to US$13.95/KG in North America. PTFE is available from numerous suppliers in various forms such as sheets, rods, tubes, and machined components.
